Human-in-the-Loop (HITL)

Human Oversight

The ability of humans to effectively monitor, intervene in, and override an AI system's outputs. The EU AI Act mandates appropriate human oversight for all high-risk AI systems, requiring technical measures that enable operators to halt or correct the system in real time.

Human-on-the-Loop (HOTL)

A design pattern where an AI system acts autonomously but a human monitors operations and can intervene if needed, rather than approving each action. HOTL balances efficiency with oversight and is appropriate for many high-risk AI use cases where full HITL would be impractical.

Agentic AI

AI systems that autonomously plan, reason, and execute multi-step tasks over extended time horizons without continuous human direction. Agentic AI is moving from demo to production in 2025–26, raising new questions around oversight, auditability, and the EU AI Act's human oversight requirements.
